Title: National marine baseline survey 1995 : littoral cell 4 : the Thames to Selsey Bill
Author: Environment Agency - National Centre for Environmental Data and Surveillance
Document Type: Monograph
This littoral cell extends from the Thames Estuary to Selsey Bill in Sussex. This constitutes approximately 2000 km2 within the coastal zone for which the Environment Agency has responsibility for controlled waters, of which 390 km2 are estuarine waters. Water quality data within this cell showed a clear geographical pattern with higher concentrations of nutrients and dissolved metals being found at those sites on the northern Kent coast towards the Thames Estuary. There were some exceptions, for example silicate showed highest concentrations around Bexhill and Beachy Head in Sussex. The Newhaven sampling site recorded a Chlorophyll-a concentration representative of bloom conditions in Summer. Although high nutrient concentrations were recorded in Summer, the area showed elevated nutrient concentrations at other seasons. Spatial Chlorophyll-a results showed that there was a distinct boundary between those waters under the influence of the Thames Estuary and those influenced by English Channel effects, with the Thames recording higher Chlorophyll-a concentrations. Sediment transport patterns within the Thames Estuary were revealed in the CASI data.
